Application plugins can insert links in an HTML page that send a request back to itself when the user clicks on them.
Using the PluginServerUrl parameter that is passed to the script, URL's can be constructed with the form:
PLUGIN_SERVER_URL/APP_PLUGIN_ID/PluginRequest?ParamStringwhere APP_PLUGIN_ID is the target plugin's ID and PluginRequest and ParamString can be whatever you like. When the user clicks on this link, the script will be run with the following INI file:
[System] Command = ProcessRequest PluginRequest = ... ParamString = ...
